| | | | | | | Ref.: | | | Pillai, 1976 (1980) (p.256, figs.F,M) |  issued from : P.P. Pillai in J. mar. biol. Ass. India, 1976 (1980), 18 (2). [p.257, Fig.3]. Female (from Port Blair, Andaman Sea): a, habitus (dorsal); b, urosome (dorsal); c, anal segment and caudal rami (enlarged); d, urosome (lateral, right side); e, urosome (lateral, left side); f, rostrum; g, A1 (distal segments, enlarged); h, Md (masticatory edge); i, distal enlargment of seta on Mxp; j, P1; k, P2; l, P5.Head and 1st thoracic segment separate, 4th and 5th fused. Posterior angles of last thoracic segment asymmetically into outwardly directed spines, left spine reaching to posterior 2/3 of the genital segment being longest. Rostrum with 2 long filaments, strongly developed. Urosomal segments and caudal rami proportions 35:17:14:12:22 = 100. Genital segment asymmetrical and with lateral swellings; anteriorly at right lateral margin it is produced externally into a recurved peg-like structure; when viewed dorsally, the left lateral margin appears uneven; ventrally genital segment has a prominent genital boss; genital pore paired, is guarded anteriorly by two sets of fine spines and with a median genital groove; at the posterior margin ventrally a cluster of 5-6 small needle-like spines present. Caudal rami symmetrical, length: width ratio = 2.8:1. A1 21-segmented, reaches the anterior margin of genital segment. Male: m, habitus (dorsal); n, urosome (dorsal); o, A1; p, P5. Nota: Urosomal segments with caudal rami proportions 13:18: 18:19 = 100. A1 19-segmented.
